what is the area of the drumhead, that has a diameter of 14 in
So the radius = 7 in
And, since we have 'circular" drumhead, it's area is given by
pi * (7)2 And using 3.14 for pi, we have
$${\mathtt{3.14}}{\mathtt{\,\times\,}}{\mathtt{49}} = {\frac{{\mathtt{7\,693}}}{{\mathtt{50}}}} = {\mathtt{153.86}}$$
And that answer is in sq in.
